New Covid Cases By State
The plot below shows the number of new COVID cases by state. Note that each figure has its own y axis; this is done so that trends can be seen within each state. Log scales can make the difference between 100 and 1000 cases hard to discern and a common y axis causes states like NY and CA to swamp states like NC. Negative new cases can occur when States revise their total number of cases downwards, as Hawaii did between June 30, 2020 and July 1, 2020.
